Description

The Transimpedance amplifier circuit was original part of a custom sensor which was created to detect magnetic longitudinal waves. The circuit converts a 1mA current in the pickup loop to a 1V reading on the output, with a sensitivity only limited by the resolution of the oscilloscope used to monitor the output. The output bandwidth is about 20 MHz but could be extended as far as 50-60 MHz with additional output filtering. This circuit, in addition to its original application as a longitudinal wave detector, can be used as a general-purpose high-bandwidth magnetic field detector.
